Here are a couple of Jain terms that start with the letter H, with simple meanings:

• Himsa: violence or harming living beings. Jainism teaches non-violence (ahimsa) as the highest ethic.
• Hinsa-rahit: free from violence; living in a non-violent, gentle manner.

If you were looking for something different (e.g., English words, or terms from a specific Jain sect or language like Prakrit/Hindi transliterations starting with H), tell me and I’ll adjust.
